Strengthening the management and service of geological samples is an important task of the land and resources department. At present, the storage of the national geological samples is scattered, the utilization rate is low, and the information level is low, far from playing its due role. As a new generation of information network technology, the Internet of Things can be used to implement intelligent management and to achieve data aggregation and sharing. Combined with the actual situation of national geological samples, the authors analyzed the feasibility and the promotion effect of the application of the Internet of Things in the management and service of geological samples, put forward the construction method of the Internet of Things of geological samples, provided a practical solution for the intelligent management of geological samples and the integrated management and application of geological sample information.
